TAG:language=chi
TAG:title=中文（简体）
index=3
codec_name=unknown
codec_long_name=unknown
TAG:language=chi

index=2

codec_name=unknown

codec_tag_string=[0][0][0][0]

codec_tag=0x0000

index=3

codec_name=unknown

codec_tag_string=[0][0][0][0]

codec_tag=0x0000

in this case，the sever cannot recognize and render the subtitle.

There is the attachement that I splited form the origin mkv useing mkvmerge tool.

It has two subtitle channels. It can be recognized and rendered in IINA palyer, but emby sever。

AI said that It is the S_TEXT/WEBVTT format，I don't know if it is correct.

So you made a small sample? Did you ensure the issue also occurs with the sample?

yes，the issue occurs with the test sample. There are the IINA shotcut and the emby server shotcut.

When I extract the subs, I get an undefined extension instead of .vtt.  Why do the subs get the undefined extension?  Are they not listed correctly in the media?  This might cause Emby player to no recognize the subs correctly.  I noticed that there is a uncommented Note at the beginning of the of one of the subtitles.  Perhaps the undefined extension works in some situations on some countries.  VLC seems to work OK. 

I can rename the extensions to .vtt as separate files and then the subs look normal.
